3 Claims.

This invention relates to goggles and more particularly to novelventilation means for the eyecups of such goggles.

One of the principal objects of the invention is to provide gogglesadapted particularly for use by welders, furnace workers or the likewith ventilation means which will prevent dirt, dust, etc., as well asinjurious light rays from reaching the eyes of the wearer.

Another object is to provide goggle eyecups of the type having openingsformed in the temporal side walls of the eyecups and having a perforatedscreen thereover in combination with a baffle internally of said eyecupsand having channel portions correlated with the inner walls of theeyecups so as to direct air from the perforated screen in the temporalsides of the eyecups inwardly of the goggle through openings formed insaid inner bafile plates adjacent the nasal sides of the eyecups withthe said inner baffle simultaneously functioning to prevent particleswhich might traverse the perforated screen rom reaching the eyes of thewearer and also for shunting light which might pass through saidperforated screen to the eyes.

Another object is to provide an inner baffle plate of the characterdescribed which will be supported in assembled relation with the eyecupsby clamping the lenses in position in said eyecups.

Another object is to provide an inner bafile plate of the characterdescribed shaped to blend with the face engaging portion of the eyecupsin such a manner as to remove any sharp edges which might have atendency to cut into the flesh and injure the wearer.

Other objects and advantages will become apparent from the followingdescription taken in connection with the accompanying drawings and itwill be apparent that many changes may be made in the details ofconstruction and arrangement of parts without departing from the spiritof the invention as expressed in the accompanying claims. I, therefore,do not wish to be limited to the exact details of construction andarrangement of parts shown and described as the preferred forms onlyhave been given by way of illustration.

Referring to the drawings:

Fig. 1 is a front elevational view of the device embodying theinvention;

Fig. 2 is a sectional view taken as on line 2-2 of Fig. 1 and looking inthe direction indicated by the arrows;

Fig. 3 is a slightly enlarged sectional view taken as on line 3-3 ofFig. 2 and looking in the direction indicated by the arrows; and

Fig. 4 is a side elevational view of the inner bafiie member.

The invention is directed particularly to the provision of ventilationmeans for goggles of the type adapted particularly for use by welders,foundry workers, furnace workers and the like who are continuallysubjected to flying particles and to relatively intense heat andinjurious light rays such as are encountered in acetylene or arc weldingor in furnaces.

The invention is directed particularly to providing means for adequatelyventilating the goggles so as to avoid discomfort to the wearer andsimultaneously protect the eyes from flying particles and from injuriouslight rays.

Referring more particularly to the drawings wherein like characters ofreference designate like parts throughout the several views, the deviceembodying the invention comprises a pair of eyecups 5 each having a faceengaging edge portion 6 shaped to the general contour shape of the faceabout the eyes. The said eyecups 5 'are preferably formed ofnon-metallic heat resisting material and more particularly of materialwhich will not readily conduct heat. The said eyecups are each providedwith a forward threaded portion I to which a lens retaining ring 8 isthreadedly connected as shown best in Fig, 2. The said lens retainingring 8 is provided with an inwardly extending flange portion 9 adaptedto overlie the lenses Ill. The said eyecups, on the temporal sidesthereof, have a side wall portion cut away to form a relatively largeopening I I therein surrounded by a shouldered seat I2. The shoulderedseat I2 is adapted to receive acover plate I3 having a plurality of ventopenings I4 therein. The cover plate I 3 is curved substantially to theouter contour shape of the eyecups and is secured thereto by rivets orthe like IS. The said cover plate I3 is provided with an integral tongueportion l6 having a slot therein for receiving the headband The openingI I extends throughout a relatively large area in the side of theeyecups to afford ample passage of air inwardly of the eyecups throughthe vent openings I4.

A baffle plate I8 is positioned internally of the eyecups and isprovided with a peripheral flange I9 adapted to overlie the forward lensretaining edge of the eyecups in between the lenses I0 and the innerflange 9 of the lens retaining ring 8. The baffle plate I8 is in theform of a cylindrical member shaped to extend substantially throughoutthe entire area of the inner walls of the eyecups and is provided with arear edge portion 20 shaped substantially to the contour shape of theface engaging edge portion 6 of the eyecups. The said edge portion 20 isflared outwardly slightly, as shown best at the location 2| in Fig. 2,,to. intimately fit with the surfaces of the inner walls of the eyecupsthroughout the inner contour of said eyecups. The said inner baflie I8is provided with spaced wall portions 22 which are bent inwardly toprovide inner channel members 23 spaced from the inner adjacent walls ofthe eyecups so as to permit the passage of air inwardly of said channelsas indicated diagrammatically by the arrows 24, Fig. 3. The said channelportions 23, adjacent the nasal ends thereof, are provided withrelatively large vent opening 25 whereby the air entering the channelsthrough the vent openings [4 may pass inwardly of the eyecups adjacentthe nasal side thereof as indicated diagrammatically by the arrows 26.The inner baffle I8 is preferably divided on the nasal side thereof asillustrated at 21 and has its wall portions 28 on the opposed sides ofthe line of division in relatively intimate contact with the innersurface of the eyecups on the nasal side thereof whereby the flow of airbeyond the inner ends of the channel portions 23 will be restricted. Thenasal side of the inner balile plate i8 is provided with an opening 29through which an eyelet 30 is adapted to extend. The eyelet 30, as shownin Fig. 3, is adapted to receive one end of a flexible chain-like bridgemember 3| which isv extended therethrough and which is locked in placeby a clamp member 32 pivoted to the inner wall of the eyecups asillustrated at 33.

The baffle plate [8 is provided with an imperforate portion 34 on thetemporal side of the eyecups lying in the rear of the cover plate I3shaped to extend in substantially parallel relation with the curve ofthe cover plate I3 and to. fit relatively intimately with the innerwalls of the eyecups adjacent the front and rear sides of the opening Il. The flexible chain-like bridge 3| is preferably covered by a tubularmember of'heat resisting material 35.

It is particularly pointed out that the outwardly flared portion 2| hasits edge surface en gaging the inner surface of the eyecups adjacent theface contacting edge 6 so as to cause the outer wall of said edgeportion 2| to lie substantially flush with the adjacent surface of theedge portion 6- thereby removing any sharp edge which might engage andcut into the'flesh of the face of -thewearer.

The inner baffie I8 is so dimensioned as to fit intimately with theinner wall of the eyecups and may be so formed as to have an initialcircumferential dimension slightly larger than the circumferentialdimension of the interior of the eyecups and thereby depending upon theslotted portion 27 to permit the said baflie to be forced intointimaterelation with the internal wall of the eyecups and to be held in saidrelation by the flange I 9 clampingly gripped between the lenses and.the adjacent edge of the eyecups.

From the foregoing description it will be seen that, simple, eflicientand economical means have beenv provdied for accomplishing all of theob- .jects and advantagesof the invention.
